A heartless man has taken the life of the mother of his one-month-old baby boy in South Africa after an altercation.

According to the SowetanLive, the 26-year-old man, said to be originally from the Eastern Cape, allegedly stabbed his 23-year-old girlfriend, Isabella Dease repeatedly, leaving her body in an open veld in President Park outside Ivory Park, Midrand.

The man allegedly killed his baby mama for refusing to have sex with him because she was breastfeeding.

The tragic incident happened on Saturday, 14 days before the start of the 16 Days of Activism for No Violence Against Women and Children campaign.

The grieving father of the deceased Charles Dease, said he wishes a death sentence could be imposed on the man who killed his daughter.

“He said to the police that he left the house with his girlfriend to buy baby clothes in Midrand. He claimed they were accosted by a black BMW with two occupants.

He said the passenger started to have a conversation with the girlfriend and it appeared the passenger and the mother of his child were acquaintances.”

Furthermore, the source said the man claimed the two men made a U-turn near Grand Central Airport and took them to a secluded area where he was pointed at with a firearm while the occupant dragged his girlfriend out of the car and stabbed her to death.

Meanwhile, further investigation into the case revealed the statement made to the police was false.

Another source said after hours of interrogation, the man finally opened up to killing his girlfriend for refusing to have sex with him since she was breastfeeding their infant.

”He confessed and he later showed the police a knife he used to kill her and also his blood-stained clothes.

After killing her he rushed to Ivory Park where he changed his black shoes and wore brown ones. We are also trying to find two missing phones of the woman.”

Isabella’s father described his daughter as a calm person, very quiet and introverted. He said his daughter studied tourism at Ekurhuleni West College, adding that the family would take care of her child.
